Abstract

The invention relates to an LED lamp panel calibration system and method applied to the calibration of an LED lamp panel. The LED lamp panel calibration system comprises a data read-write module and a calibration module, wherein the data read-write module is used for writing first chroma correction coefficients from an LED control card electrically connected with an LED light panel to be calibrated into a nonvolatile memory of the LED light panel to be calibrated for storage and reading data stored at specified positions of the nonvolatile memory of the LED light panel into the LED control card to obtain second chroma correction coefficients; the calibration module is used for calibrating whether the first chroma correction coefficients are in accordance with the second chroma correction coefficients to determine whether the first chroma correction coefficients are correctly stored into the nonvolatile memory. The LED lamp panel calibration system and method changes a human eye subjective judgment inspection method of a lamp panel Flash into an objective automatic calibration method, solves the non-objective problem of calibration results, enables calibration working of the lamp panel Flash can be added to a production line and promotes popularization of the light panel Flash technology.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED lamp board verification system and a LED lamp board verification method. Background technique [0002] Existing LED display manufacturers have gradually adopted the light board Flash to store the correction coefficient of the light board. After using the light board Flash to store the correction coefficient, when replacing the light board, the light board can be directly read from the light board Flash. The correction coefficient of the lamp panel does not need to be re-calibrated in the area of ​​the lamp panel, which simplifies the process of replacing the lamp panel on site. [0003] However, if the Flash of the module is damaged or the transmission data has a code error, etc., the stored correction coefficient will be incorrect, so that when the module is replaced, the correction coefficient in the Flash of the module cannot be directly used, and it needs to be performed ...
